Organizers are reminding attendees that just because the counter-culture festival in the Nevada desert is known for occasional nudity and kinky landmarks like the "Orgy Dome," it doesn't mean it's a free-for-all when it comes to touching or nonconsensual sex, the Reno Gazette Journal reported. This year's event started this weekend.

While the festival doesn't have official guidelines, it does have a set of informal rules.

Tex Allen, a 13-year Burner, doubts many newcomers to the playa are reading those.

Many of those reports involve leering or grabbing, which aren't considered sexual assault under Nevada law. A few reports each year require involvement from law enforcement.

Last year, two people were arrested on suspicion of sexual assault without substantial bodily harm.

No arrests related to sexual assault or rape were made the year before.

Despite the low arrests, Donna Rae Watson, director of the Bureau of Erotic Discourse, a large camp at Burning Man that teaches people about sex, still hears stories of harassment at the festival from dozens of people each year.
